woonwonknvs STICKER on MOLDER-HEAD.

T 0 all whom it may comem:

Be it known that 1, JOHN of the United States, and resident of Waukesha, in the county of Waukesha and State of WVisconsin, have invented new and useful Improvements in Woodworking Stickers or Molder-Heads, of which the following is a description, reference being bad to the accompanying drawings, which are a part of this Specification. I

The present invention relates to certain new and useful improvements in woodworklng molder heads and refers more particularly to a cutting bladeattaching member securable thereto in different ad usted posltions.

It is thepresent custom in the manufacturing of molding, window guide frames,

, and the like, to employ a number of cutting knives of various shapes and sizes secured to a revoluble head, some of the knives'curving or shaping the wood and others severing or cutting. Considerable fault has been found with the present method of severing or cutting the wood, as oftentimes the cutting knives will strike a hard knot in the wood and break the point thereof, as a result of which the wood is mutilated and the finished product will not run true.

Hence with the above and other inherent objections in mind, my invention has for one of its objects to eliminate the cutting or severing knives now commonly used and to substitute therefor saw blade members which will efiiciently perform the functions of the cutting knives. v

Another object of this invention is to provide an improved form of attaching member for a cutting saw blade of the class described, which is readily adjust'ably secured to a revoluble head.

A further object of my invention is to provide an attaching member of the class described and aclamping plate forsecuring the cutting saw blade to the attaching member all of which have means cooperating with means on the revoluble head to provide a ri id connection therebetween.

/fith the above and other objects in view which will appear as the description pro: ceeds, my invention resides in the novel construction, combination and arrangement of parts substantially as hereinafter described and more particularly defined by the appended claims, it being understood that such changes in the precise embodiment of the SHUFF, a citizen 4 Sp'ecificaticn of Letters Patent. Patlented Sept, '21., 1920; Application filed April 15, 1920. Serial No. 374,175, i

herein" disclosed invention may be made as 3 come withinthe scope of" the claims.

In the accompanying drawing I have ing sticker or molder head equipped with my improved device, said View being taken on the plane indicated by the line 1-1 of Fig. 2

Fig. 2 is a side elevation of one end of a woodworking sticker or molder heac equipped with my device. V

V Fig. 3 is a perspective view of one of my improved attaching members and saw blade secured thereto.

Fig. 4 is a perspective view'ofone of the improved saw' blades detached from the attaching member.

Fig. 5 is a perspective view of one of the attaching members with the clamping plate and cutting blade detached therefrom, and

Fig. 6 is a perspective view of a slightly modified form -of attaching member, with the cutting blade and clamping plate del tached therefrom.

Referring now more particularly tothe accompanying drawing, 10 deslgnates a woodworking sticker or molder' head of usual construction having a supporting drive shaft 11 and pro'vided in each face with an inverted T-fslot 12, the head having secured thereto alternate cutting members nowto be described; Cutting knives13 and 14 are secured to opposite faces of thehead by means of securing bolts 15., which knives are of any shape necessary't'o'producethe particular kind of molding or the like desired.

Secured to the next face and following the blade 13, and centrally thereof, is a saw. blade'16 for severing the material being worked upon after the knife 13 has shaped the same, thus producing in a single operation two strips of completed material.

The knife 16 is secured to an attaching member 17 by means of a clamping plate 18, the attaching member having two spaced apart depending lugs or projections 19 and 20 on its under face for engagementin the adjacent slot 12 and said member is rigidly, but readily adjustably, secured to the head by means of a bolt 21 having its head posiis of the desired shape and is followed by tioned within the transverse portion of the T-slot 12. The bolt 21 passes through an aperture 22 within member 17 intermediate the lugs 19 and 20 and the end of said member to which the saw blade 16 is secured is enlarged to provide an attaching head 23. The head 23 is notched or recessed adjacent the aperture 22 to permit the insertion of a wrench over the bolt 21.

The outer peripheral edge of the clamping plate 18 forms a continuationof the head 23, and both the plate 18 and blade 16 are formed with projections 25 and 26, respectively, on their inner edges for engagement in the slot 12. The blade 16 is securely clamped between the outer face of the head 23 and the clamping plate 18 by means of securing screws 27 passing through alined openings in said plate and saw blade and having threaded engagement with openings 28 in the head 23.

The outer cutting edge of the teeth 16 form an arc of which the axis of the head 10 is the center, and this are may be increased or decreased to suit the work desired by changing the sizes of attaching member and blade carried thereby.

The knife 1% follows the saw blade 16 and another blade 16, and as the description of the same and its attaching member is identical with that just described, the description of the other blade 16 will sufiice.

In view 6 I have illustrated a slightly modified form of attaching member provided with a head 23 at each end thereof so that the same may be used with the cutting blade 16 on either end. With that form of attaching member depicted in Fig. 3 if it is desired to cut close to the end of the head 10 remote from the part 23 of the attaching member, it is necessary to provide an attaching member with a head 23 on the opposite end thereof. With that form of my invention depicted in Fig. 6, the saw blade 16 may besecured to either end thereof and thus one attaching member will eliminate the necessity of using two sets of attaching members, one right handed and one left handed.

As will be readily apparent, the relative positions between the knives and cutting blades may be changed at will according to the work being performed, and it will be readily apparent to those skilled in the art to which an invention of this character appertains that I provide an improved cutting saw blade and attaching member thereforwhich will be practical and efficient for the purpose described.

l/Vhat I claim as my invention is:

1. In a device of th class described, the combination with a revoluble head having a slot therein, of an attaching member engageable with the revoluble head, a projection on said attaching member for engagement in the slot of said head, a cutting member, a clamping plate for securing the cutting member to the attaching member, a projection on said clamping plate for engagement in the slot of said head, and means for securing the attaching member to said head.

2. in a device of the class described, the combination with a revoluble head having an inverted T-slot therein, of an attaching member engageable with the revoluble head, two depending spaced lugs formed on the attaching member for engagement in the slot of said head, a saw blade provided with a lug engageable in said revoluble head slot, clamping plate for securing the saw blade to the attaching member, and means for securing the attaching member to the revoluble head.

3. In a device of the class described, the combination with a revoluble head having an inverted T-slot therein, of an attaching member engageable with the revoluble head, two depending spaced lugs formed on the attaching member for engagement in the slot of said head, a saw blade provided with a lug engageable in said revoluble head siot, a clamping plate for securing the saw blade to the attaching member, a projection on the inner edge of the clamping plate for engagement in the slot of the revoluble head, and means for securing the attaching member to said head.

4. In a device of the class described, the combination with a revoluble head having a slot therein, of an attaching member engageable with the revoluble head, an enlargement, forming an attaching head at each end of said member, a cutting member securable to either of said attaching heads, clamping plate for each attaching head for securing the cutting member thereto, and means for securing the attaching member to said revoluble head.

In testimony whereof, I my signature.

JOHN SHUFF.
